3.1. Overview
The MCP-J20 series pressure sensor uses a MEMS piezoresistive core as a pressure sensitive element, which outputs a raw signal proportional to the ambient pressure. The conditioning chip with a built-in 16 bit ADC drives the sensitive component and amplifies, temperature compensates, and linearizes the original signal to output an analog voltage output signal that is linearly related to the applied pressure.
